If `vecpxxvecq=vecr and vecp*vecq=c,` then `vecq` is

Given vecP. vecQ=|vecPxxvecQ| and vecR=vecP+vecQ then |vecR| is

If vecP+vecQ=vecR and vecP-vecQ=vecS , prove that vecR^2+vecS^2=2(vecP^2+vecQ^2)

If vecP + vecQ = vecR and vecP - vecQ = vecS , then R^(2) + S^(2) is equal to

If vecP + vecQ = vecR and vecP - vecQ = vecS , then R^(2) + S^(2) is equal to

if vecP +vecQ = vecP -vecQ , then

if vecP +vecQ = vecP -vecQ , then

Suppose that vecp, vecq and vecr are three non-coplanar vectors in R^3 . Let the components of a vector vecs along vecp, vecq and vecr be 4,3 and 5 respectively. If the componenets of ths vector vecs along (-vecp+vecq+vecr), (vecp-vecq+vecr) and (-vecp-vecq+vecr) are x, y and z respectively, then the value of 2x+y+z is.
